Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The shooting method, the shooting device, the electronic equipment and the readable storage medium provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 1, one of flowcharts of a photographing method provided in an embodiment of the present application is shown. The shooting method provided by the embodiment of the application can be applied to electronic equipment. In practice, the electronic device may be an electronic device such as a smart phone, a tablet computer, a laptop portable computer, and the like. The electronic device may have a camera application installed therein, and the camera application may have a photographing function.

The shooting method provided by the embodiment of the application comprises the following steps:

step 101, controlling a camera to shoot N groups of images of N shooting objects, wherein each group of images comprises an object image and a background image.

In the present embodiment, an execution subject of the video photographing method (e.g., the electronic apparatus described above) may be mounted with a camera. The execution body may control the camera to capture N groups of images of N capturing objects. Wherein N is a positive integer. The N shot objects may be any N objects in the video preview interface, such as people, animals, stills, scenes, etc. As an example, if a child, a woman, and a tree are displayed in the photographing preview interface, at least one of the child, the woman, and the tree may be a photographing object. For each subject, when the camera is controlled to shoot the shooting subject, shooting after focusing can be performed on the shooting subject first.

In the present embodiment, N groups of images can be obtained by photographing N photographing subjects. Each set of images may include an object image and a background image. The object image may be an image area surrounded by an object contour of the photographing object, and the background image may be an image of an area other than the image area surrounded by the object contour in the photographed image. The object image may be an image including the image region, and the background image may be an image including a region other than the image region, for example, the object image and the background image may each include the entire image content in the video preview interface.

In some optional implementations of this embodiment, before controlling the camera to capture N groups of images of N capturing objects, the executing body may further receive a second input from the user to N preview areas on the capturing preview interface; in response to the above-described second input, an object in each of the N preview areas may be determined as a photographic object. The second input may include, but is not limited to, a sequential click input, a sequential long press input, a sequential circle selection input, a sequential box selection input, etc. for each preview area of N. Thus, the user can flexibly select the shooting object in the shooting preview interface according to the requirement.

In some optional implementations of this embodiment, after determining the object in the preview area as the shooting object, the executing entity may further mark the shooting object in the video preview interface. The marking means may include, but is not limited to, at least one of: a mark frame is displayed on the subject, a logo is displayed beside the subject, a style of a preview area where the subject is located is changed, and the like. As an example, fig. 2 shows a schematic diagram of a marking process of a photographic subject. The shooting preview interface comprises three shooting objects, namely a female near, a child in a middle distance, and a tree and a bench far away. The user may first click on a nearby female, and a number 1 appears next to the corresponding female outline, identifying it as the first subject. The user can continue to click on a child at a medium distance, where a number 2 appears next to the child's outline, indicating that it is the second subject. Therefore, when a user selects one shooting object, a corresponding selection result can be displayed, so that the user can conveniently distinguish the selected shooting object from the unselected shooting object, the user is prevented from repeatedly selecting or cancelling the same shooting object by mistake, and the accuracy of the user operation is improved.

It should be noted that, in this process, if the user wants to cancel a certain shooting object, the user may click on the main body again, and then click on the "change setting" control to cancel the selection of the shooting object. When the user "completes setting" the control, the process of selecting the photographic subject may end.

In some optional implementations of this embodiment, after the camera is controlled to capture N sets of images of N photographic subjects, N subject images may be displayed in the first region and N background images may be displayed in the second region. The first area and the second area may be any two areas in the display interface. As an example, three photographic subjects, respectively a near female, a middle-distance child, and a far tree, are included in the photographic preview interface. After controlling the camera to take three sets of images of the three photographing subjects, the photographing result display interface may be as shown in fig. 3. The upper area of the shooting result display interface is a first area, and can display an object image of a close-up woman (as shown by a reference numeral 301), an object image of a distant view tree (as shown by a reference numeral 302), and an object image of a middle-view child (as shown by a reference numeral 303). The lower region of the photographing result display interface is a second region, which may display a background image of a near female (as indicated by reference numeral 304), a background image of a distant tree (as indicated by reference numeral 305), and a background image of a middle-sized child (as indicated by reference numeral 306). By displaying the object image and the background image in the divided areas, the user can conveniently distinguish the object image and the background image, and convenience is provided for the user to select the target object image and the target background image in a candidate manner.

In some optional implementations of this embodiment, when controlling the camera to capture N groups of images of N capturing objects, focusing and capturing may be performed on each capturing object first, so as to obtain a first intermediate image. Then, an image of a first area in the first intermediate image may be scratched to obtain an object image, where the first area may include an area surrounded by an object contour of the photographing object. Finally, a background image of each photographic subject may be obtained based on the first intermediate image or the second intermediate image. The second intermediate image may be obtained by focusing and photographing a second area, and the second area may be an image area of the first intermediate image other than the first area. The object image and the background image obtained by the method can clearly display different shooting objects and blurring effects of different degrees, and provide convenience for a user to distinguish and select shooting objects needing clear display and blurring effects. As an example, as shown in fig. 2, three photographic subjects, respectively, a close-up woman, a middle-view child, and a distant-view tree, are included in the photographic preview interface. The near-field woman may be first focused and photographed to obtain a first intermediate image of the near-field woman. Then, the region where the near-field woman is located in the first intermediate image may be taken as the first region, so as to obtain the object image (as shown by reference numeral 301 in fig. 3) and the background image (as shown by reference numeral 304 in fig. 3) of the near-field woman. And then, focusing and shooting the long-range trees to obtain a first intermediate image of the long-range trees. Then, the area where the tree in the first intermediate image is located may be taken as the first area, so as to obtain an object image (as indicated by reference numeral 304 in fig. 3) of the distant view tree and a background image (as indicated by reference numeral 305 in fig. 3). Then, focusing and shooting can be carried out on the middle-view child, and a first middle image of the middle-view child is obtained. Then, the region where the child is located in the first intermediate image may be taken as the first region, so as to obtain an object image (shown as reference numeral 303 in fig. 3) of the middle-view child and a background image (shown as reference numeral 306 in fig. 3). By displaying the object image and the background image in the divided areas, the user can conveniently distinguish the object image and the background image, and convenience is provided for the user to select the target object image and the target background image in a candidate manner.

In some optional implementations of this embodiment, when the background image of each photographic object is acquired, the background image may be obtained by matting out the image of the second area in the first intermediate image. For example, as shown in fig. 2, three photographic subjects, respectively, a close-up woman, a middle-view child, and a distant tree are included in the photographic preview interface. For the first intermediate image of the near-field woman, the first region may be a region where the near-field woman is located, and the second region may be an image region other than the near-field woman. The background image can be obtained by buckling the image area outside the close-range female. For middle-view children and long-view trees, the same principle is not repeated here. Therefore, for different shooting objects, background images with different blurring degrees can be obtained, and a user can flexibly select the background images with the needed blurring degrees.

In some optional implementations of this embodiment, when obtaining the background image of each shooting object, focusing and shooting may also be performed on the second area first to obtain a second intermediate image; then, the image of the second area in the second intermediate image can be scratched to obtain a background image. For example, as shown in fig. 2, three photographic subjects, respectively, a close-up woman, a middle-view child, and a distant tree are included in the photographic preview interface. For the first intermediate image of the near-field woman, the first region may be a region where the near-field woman is located, and the second region may be an image region other than the near-field woman. The second intermediate image may be obtained by focusing on areas of the image other than the near women, such as on the far. And then buckling an image area outside the close-range women in the second intermediate image to obtain a background image. For middle-view children and long-view trees, the same principle is not repeated here. Thus, a clear background image can be obtained. On the basis, the blurring degree of the background image can be further adjusted, so that a user can obtain clear background images and background images with different blurring degrees, and blurring effects are further enriched.

Step 102, a first input of a user is received.

In this embodiment, the execution body may receive a first input from a user. Wherein the first input is operable to select a target object image and a target background image from the N sets of images. The first input may include an input of an object image and an input of a background image of the N sets of images. The input may include, but is not limited to, a click input, a long press input, a circle selection input, a box selection input, and the like. The execution body may set a certain object image as the target object image after detecting an input of the user to the object image. Similarly, the execution body may set the target image as the target background image after detecting the input of the user to a certain background image.

And step 103, in response to the first input, performing image synthesis on the target object image and the target background image to generate a target virtual image.

In this embodiment, in response to the first input, the execution subject may perform image synthesis on the target object image and the target background image, to generate the target virtual image. In the target blurring image, the target object image selected by the user can be clearly displayed, and other areas can be displayed in a blurring effect. When the target object image and the target background image are combined, an image region surrounded by the object outline of the photographic subject may be first clipped from the target object image. And then, aligning the buckled area with an area surrounded by the object outline of the corresponding shooting object in the background image. And finally, covering the buckled area in the aligned area, thereby obtaining the target blurring image.

In some optional implementations of this embodiment, the execution subject may receive user input of at least one of the N object images and at least one of the N background images. In response to the input, the at least one object image may first be determined as a target object image and the at least one background image may be determined as a target background image.

As an example, in one shot scene, a close-up woman, a middle-view child, and a distant-view tree are included. After the camera is controlled to shoot three groups of images of the three shooting objects, an object image of a near-scene female, an object image of a distant-scene tree, an object image of a middle-scene child, a background image of the near-scene female, a background image of the distant-scene tree and a background image of the middle-scene child can be obtained. If the user needs to obtain images that can be clearly displayed by both a woman in the close-range and a child in the middle-range and the rest of the images are displayed in a virtual manner, as shown in fig. 4, the user can click on two photos, namely, an object image of the close-range woman (shown as a reference numeral 401) and an object image of the child in the middle-range (shown as a reference numeral 402), and at the moment, the edge of the picture becomes dark, and then the user indicates selection, as shown in fig. 4.

Next, a photograph of background blurring may be selected. The degree of background blurring is also different due to the different focus positions of the subject. According to the optical principle, the closer the lens is to the shot object, the higher the background blurring degree is. Therefore, if the user wishes to have a high degree of blurring of the distant view, a background image of a near-view female can be selected. If the user wishes to have a lower background blurring or does not blurring, a background image of the distant scenery tree can be selected. Here, the user desires the background to be moderately blurred, and a background image of a child with a medium scene may be selected (as shown by reference numeral 403). On the basis, the execution subject can synthesize the images selected by the user to obtain the target blurring image with the blurring effect required by the user. In the target blurring image, near women and middle-range children can be clearly displayed, and other areas can be subjected to blurring display according to the middle blurring degree. Therefore, the user can freely select the shooting object which is wanted to keep clear and the area which is wanted to be virtual, the selected shooting object is not needed to be in the same focusing plane, and the effect of image blurring is enriched.

As yet another example, for the same shooting scene, if the user needs an image that is clearly displayed by a woman in close-up and is displayed with the rest of the area being blurred, the object image of the close-up woman may be clicked. Next, a photograph of background blurring may be selected. If the user wishes to have a high degree of blurring of distant views, a background image of a near-view female can be selected. If the user wishes to have a lower background blurring or does not blurring, a background image of the distant scenery tree can be selected. If the user wishes the background to be moderately blurred, a background image of a child with a medium scene may be selected. In addition, the user can select two or more background images. For example, if the user selects a background image of a close-range female and a background image of a medium-range child, the degree of blurring may be between a high degree of blurring and a medium degree of blurring, i.e. at a medium-high degree of blurring. On the basis, the execution subject can synthesize the images selected by the user to obtain the target blurring image with the blurring effect required by the user. In the target blurring image, a close-range female can clearly display, and other areas can be subjected to blurring display according to the middle-high blurring degree. Therefore, the user can freely select the shooting object which is wanted to keep clear and the area which is wanted to be virtual, the selected shooting object is not needed to be in the same focusing plane, and the effect of image blurring is enriched. In some optional implementations of this embodiment, the receiving the first input from the user may further include receiving an input from the user to a target background image of the N background images, where the input may be used to set a target blurring degree of the target background image. The input may include, but is not limited to, a click input, a double click input, a long press input, a swipe input, a custom gesture input, and the like. Thus, according to the first input, the execution subject can also determine the target blurring degree of the target background image. In the image synthesis, the blurring process may be performed on the target background image according to the target blurring degree. Then, the target object image and the target background image after blurring processing can be subjected to image synthesis to generate a target blurring image.

As an example, the user takes a close-up woman as a photographing object, and selects an object image of the group of images as a target object image. Then, the background area is photographed again, and the clear background image is selected as the target background image. At this time, as shown in fig. 5, the target object image and the target background image may be displayed in a photographing result display interface (as shown by reference numeral 501) (as shown by reference numeral 502). After the user presses the target background image for a long time, a blurring-degree custom interface may be displayed (as shown by reference numeral 503). The blurring degree custom interface may have displayed therein a "background clear does not blurring" control (as shown at reference numeral 504) and a "blurring strength" control (as shown at reference numeral 505). In the "blurring strength" control, a slider for setting the blurring degree may be displayed. If the background blurring is not needed, the user can click on the background clear blurring control. If background blurring is required, the user can complete by sliding the slider in the "blurring strength" control.

If the user selects the background definition without blurring control, the blurring degree configuration information can indicate that the blurring degree is zero, and blurring treatment with the blurring degree of zero can be performed on the clear target background image at the moment, so that the obtained blurring background image is the original clear target background image. If the user selects the blurring strength control to control the slide rail to be positioned at the center of the slide bar, the blurring degree configuration information can indicate that the blurring degree is 50%, and blurring treatment with the blurring degree of 50% can be performed on the clear target background image at the moment, so that the target background image after blurring is obtained. The blurring degree of the target background image is controlled through user interaction, so that the blurring degree of the target background image can be improved, the definition of the target background image can be improved, the blurring effect is further enriched, and the flexibility of blurring shooting is improved.

The user may input the target background image out of the N background images, slide up and down, slide left and right, or determine the blurring degree according to the sliding direction and/or the sliding distance, and the like, and the input is not limited to setting on the control.

According to the method provided by the embodiment of the application, N groups of images of N shooting objects are shot through the control camera, each group of images comprises an object image and a background image, and then a first input of a user is received, so that image synthesis is carried out on the target object image and the target background image in response to the first input, and a target blurring image is generated. Therefore, on one hand, under the condition that the camera is not increased, the continuous zooming of the single camera is controlled to shoot a plurality of images, and the generation of the blurring image is realized by combining the interactive operation of a user, so that the blurring shooting cost is reduced. On the other hand, the user can flexibly select the target object and the background blurring effect which need to be clearly displayed, the selected target object is not limited by a focusing plane, the target blurring image meeting the blurring effect required by the user can be obtained, and the blurring effect of the image is enriched.
